You'll need two cups of fresh watermelon. I used half of a personal seedless watermelon (it was a fairly large personal watermelon)

Put watermelon in a food processor or blender and puree until smooth

You should have about a cup and a half of puree

Pour puree through a strainer to strain out thicker pulp and any seeds

This will leave you with about one cup of watermelon juice

Heat apple cider and lime juice in a smal sauce pan until juice is just hot, but not boiling. If liquid boils allow it to cool for a few minutes

Sprinkle gelatin packets over cold watermelon juice and let stand for one minute

Add gelatin mixture to the hot apple juice and stir for about five minutes until gelatin is completely dissolved

Pour mixture into eight ramekins so they are about 3/4 full

Refrigerate cups for 30 - 60 minutes so gel just starts to solidify. It makes a difference if the cups are covered or not. Covered cups will take longer to solidify. If not covered they'll probably ready to add the fruit after 30 minutes

Add berries to the gel cups

Refrigerate cups for at least two more hours until gelatin is set

Store covered in refrigerator
